 Python string translate() function replace each character in the string
 using the given translation table. We have to specify the Unicode code
 point for the character and ‘None’ as a replacement to remove it from
 the result string. We can use ord() function to get the Unicode code
 point of a character.
 -------------------------------------------------------------------------
 s = 'abc12321cba'
 print(s.translate({ord('a'): None}))
 Output: bc12321cb
 -------------------------------------------------------------------------
 If you want to replace multiple characters, that can be done easily using
 an iterator. Let’s see how to remove characters ‘a’, ‘b’ and ‘c’ from a
 string.
 --------------------------------------------------------------------------
 s = 'abc12321cba'
 print(s.translate({ord(i): None for i in 'abc'}))
 Output: 12321
